Category: Biliary Stents  

The Niti-S & ComVi Biliary Stent consists of the implantable metallic stent and introducer system. The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis which has radiopaque markers on each end and at the center. The Stent is loaded in introducer system and upon deployment the stent imparts an outward radial force on the luminal surface of the bile duct to establish patency. Niti-S Full Covered Biliary Stents used in benign stricture can be removed; (see Warnings). Full Covered Biliary Stents can be repositioned after deployment (see Warnings).
